They usually run stockers, it isn't that steep anymore (used to be 3 yrs ago) Just really whooped out anymore.
Most people are running stockers, haven't seen any marvin shaws there yet. The parkinglot is right next to the hill. You don't have to ride much more then 300ft to the hill. Directions driving all the way to the hill can be tricky, pm me if you want them.
I'll post some more close ups when I get home, the whoops are pretty big at the bottom. In alot of cases a race can be lost at the bottom. Its certainly not the biggest hill there, but it is the widest, and most open.
Beware, there can be alot of stupid people out there on weekends.
